never ridden a ti bike before. but generally ti is known to be in between alu and steel in terms of stiffness. but it depends on the design. it can be made plenty stiff. do some search on the internet, like "bicycle frame materials" etc. and read some of the reviews on the internet. some of the ti bike manufacturers are litespeed, lynskey, moots, van nicholas, serotta, to name a few.

i'd go with a used one if budget is limited. if money is not an issue, of course get a new one.

Ben, our 3rd in rank is asking where are you. Report in the first thing in the morning, K?

Go this today in my post box. The 4mm longer axle pedal for my odd feet position and to prevent my shoe rubbing with the crank. Came with blue cleat too but i will still be using yellow cleat.
